Improvement of IEC 60534-8-3 standard for noise prediction in control valves

The current IEC standard for predicting aerodynamic noise in control valves regulating the flow of gases and vapors is being revised by Working Group 9 of the IEC Subcommittee 65B. The first is a uniform method of measuring the radiated noise from the valve and the associated test piping including fixed flow 6053 through which the test fluid water is passing.
